Social scientists have noticed that one partner’s behavior can influence the other – and it looks like this was a classic example of good habits rubbing off.

My girlfriend and I have been living together for almost six months. During that time, she’s adapted to my sleeping schedule and now goes to bed and wakes up at roughly the same times as I do. Keeping a set bedtime and risetime — even on the weekends— is a hallmark of good sleep hygiene and good sleep.

Now that she’s turning in at about the same time I am – instead of staying up much later and cutting into her total sleep time – she gets way better sleep now than before.
